SHUTTLE.

Specification of Letters Patent.

Patented Oct. 10, 1916.

Application filed January 27, 1916. Serial No. 74,610.

To all whom it may concern:

Be it known that I, WILLIAM F. GOM- IsKY, a citizen of the UnitedStates, and a resident of Middletown, in the county of Middlesex andState of Connecticut, have invented a new and Improved Shuttle, of whichthe following is a specification.

My invention relates to the class of clevices above named, and an objectof my invention, among others, is to provide a device of this kindhaving means to effectively support a bobbin in a manner to prevent thethread from sloughing off.

One form of device embodying my invention, and in the construction. anduse of which the .objects herein set out, as well as others, may beattained, is illustratedin the accompanying drawings, in which Figure 1is a side view of a shuttle embodying my invention, with parts brokenaway to show construction. Fig. 2 is a view looking at the shuttle froma point located at right angles to the point of view of Fig. 1. Fig. 3is a view in cross section through the shuttle on plane denoted bydotted line 33 of Fig. 1, the bobbin being removed.

Fig. 1 is a detail view showing a slightly different construction ofmeans for attaching the spring to the base.

In the operation of weaving, as is well understood, the shuttle isthrown with great force and is suddenly brought to a stop at each end ofits path of travel with aresult that the thread must be wound securelyupon the bobbin and the bobbin must be securely fastened in place towithstand such force, and in the uses of some kinds of thread, andparticularly silk, it is almost impossible to prevent the silk fromsloughing ofi from the end of the bobbin by reason of the suddenstopping of the shuttle in its travel.

It is a purpose of my present invention to provide means for resilientlysupporting the bobbin so that the jars and vibrations incident to thesudden stopping of the shuttle will not be suflicient to remove thethread from the bobbin or the bobbin from the spindle, these means ofsupport being so constructed that they will also effectively resist theforce incident to such action. Such a device is shown in theaccompanying drawings in which the numeral 5 indicates a shuttle casehaving a recess 6 within which a base 7 is rotatably mounted upon a Ipivot. 8, said base. being held in predate positions by means at aspring 8,12.

ipindle 1O projecting from the end of the ase.

All of the parts thus fardescribed are of old and well knownconstruction, and, except in connection with the parts to be hereinafterdescribed, constitute no part of my present invention.

In carrying out my idea a spring is secured to the side of the base toprovide a resilient support for a bobbin on the spindle, in one form ofdevice this spring being attached by means of a clip 11 that isremovably secured to one side of the base 7. A backturned part 12 fromthe clip provides space within which the end of the outer coil 13 of thespring is received and within which it is clamped and securely held bycausing said back turned part to firmly bind theend of the spring in anysuitable manner. This spring is preferably formed of flat metal ofconsiderable width preferably disposed in conical form as shown in Fig.1 of the drawings, it being noted that the spring is under fullcompression and that if relieved the side toward the base would assume aconical form as well as the opposite side. A sleeve 14 projects throughthe inner coil of this spring, a flange 15 on this end of the sleeveresting against the coils of the spring. This sleeve is provided with aswelled portion 16 to fit snugly within the quill 17 of the bobbin tohold the latter in place by frictional engagement, this sleeve and thequill being of well known construction.

The clip 11 is secured in place as by means of a screw 18 threaded intothe base 7, said screw passing through a slot 19 in said clip. Atensioning lip 20 may be formed on the end of the clip to engage theedge of the base, or with tensioning shoulders constituted by grooves 21in the side of the base, so that the clip may be placed in variouspositions, and the apex of the cone of the spring resting against thebase, this change of the position of the clip will regu late the tensionof the spring. A spring holding plate 22 may be secured in place by thescrew 18, the end of this plate, when employed, resting against the edgeof the spring and holding it from displacement withinthe backwardlyturned part of the clip. The end of the spring may be enlarged as at 23,any suitable manner to prevent its withdrawal endwise of the springtrain underneath said baakturned spect to the sleeve, I provide meansfor holding the latter. In one form of construction I produce thisresult by making the spindle of angular shape at its base, 2%, thesquare form being preferable, and by making the sleeve lat ofcorresponding shape to fit the spindle at this point as shown in Fig. 3of the drawings, the sleeve will be held from turning movement with thequill when the latter is twisted to loosen it. This result may beattained in many different ways that will readily suggest themselves tothose skilled in the art.

In Fig. 4 of the drawings there is shown a clip 26 that is formedintegral with the spring as one means for securing the latter to thebase 7, it being my purpose to use this form of clip with the deviceshown in Figs. 1 and 2 if desired.

lVhile I have shown and described herein a satisfactory construction ofdevice embodying my invention, this may be departed from to a greater orlesser degree and yet be within the spirit and intent of the invention.
